To ZZ 'whom "it may concern.: i A

Beit known that I, Roseau: fH. RUSSELL,

t a citizen 'of 'the 'United xStates, residing at ,lVorlan'ch 'in the"con'nt'y off Va-s'h'akie and State of vllyoining, 'have inventedcertain new and useful Improvements Framing Bevels, of which thefollowing "is a specifi cation.

The y.present invention .appertains "to improvements incarpeiiterstools, known more ,particularly as fra-ming 'bevels, and #it has for itsprimary .object `top`rgovi de a 'conyenient Vdevice .especially.iisefii'l laying off of certain rafters entering in'tobuildingconvstruct-ions.

lt 'may be well krto Vear-(plain that talthough the steel square isprobably the most 'used of all carpenters tools, and in .spite offthefact Avthat .this Atool is y.capable of bein-g effectively employed inrafter framing, comparatively Afew ofits users are sniciently conversantwith it to enable `its employment 'for this purposeparticularly in 4thelframing yof hips, valleys, jaolzs and other cripple irafters. It is,therefore,.myiobjeet toY .devise .a handy tool inthe form -ofa bevelhaving blade members thereon, each 'bearing pnoper\data for the use oftheJ square yandrso ,formed as to be .quickly -set for use in ltheylaying off .of .a raf-ter for the lusual .set pitch or Epitches .andwhich withontfurther adjustment .serves `for olf `the .pluim-b fand sidecuts lof jacks and other cripples.

More par-tilcularly speaking, `my invention .embodies1.astoclror 'handle.and a plurality Vof blades yadjustable 'toimake predetermined angleswith -respectftojthe stock, ',tliefedges ofleac'h blade having adefinite .fixed angular relation to lthe* stock such that 'one v.ed-gemay beutilized for themarlzing olf offpluinb cuts while the other4ofgthese edges, fwithout altering the angular adjustment, will servefor the marking olf of 4cheek or :side cuts. In those devices of ythis.character which have heretofore ybeen proposed, ythis only capable @ofbeing accomplished lby 'a Lohan-ge of the adjustment 'of `ithe 'bladesand therefo-re witlrmy meansof operation the l-ayin g r.off of anglesjisgreatly facilitated.. v

lVith the abo-ve :and-.other .objects in view, the vinvention vconsistsincertain combinations and ai-rangementsofthe parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed ont in the appended claims.

Inthe drawing: Figure l is a side elevation 'of 'a framing bevel,constructed in accordance with this invention, the blades :being Tinnormal closed position.

' Corresponding and like parts are rreffnred to lin 'the following`description andl indil cated 1n all of the lviews 'offthe draxvi'ngs,by like reference characters.

Referringfto'the drawing, l designatesthe Ibody portion or v"stock of:the bevel device which is V"provided with a'central :slotiQ of"Suiiicielit size lto receive a plurality Aof rblade members, generallyindicatedfbyjthe reference `clrara'cter B, there beingin the present"instance 'iiv'e of suchbla'de members, abl'ade for each of thefollowing Aroof pitches:

One-quarter, one-third, lthreeleigliths,fiver-twelfth@ and one-half,these blades being designated "cl/,'31, 0, da and le 'The 'blades arepiivotally secured to fthe Aend yof vthe lstock upon the pintle 4fvhaving a thuinbfnut or head, 5 "by means of 'which the. 'meinbermay beadjusted to `produce 'sufiici'ent amount of 'friction to hold "theblades in their particular adjusted v'positions. For this kpurpose vkthepifntle ,4 'passes through a yferru'le '6 which embraces lthe stock on'three sides, this ferrule Kjbeingjcut away at the end so as to formy astop yshoulder 7 which is common toy all of the "blade members. y n

The opposite .end of the bevel is ,prefer- Aably provided with a metalprotector 8 so as to fprevent splitting of `the stock. AOne side of thehandle is .cut :away as indicated at .9 to permit ready vaccess-tothe'blades for openingthe ydesired one, each blade "having`21S-'fingernail notch 10f-to facilita-te the `opening operation. y

Referring particularly to Figure 3, it will be observed that eachindividu-al blade has llO the same general configuration but the bladesvary in width so as to present two distinct marking edges, one indicateda: and the other y. In other words, these two edges when the blade isopened to its adjusted position with the shoulder 11 thereof abuttingagainst the stop shoulder 7 ofthe ferrule have a distinct angularrelation with respect to the inner edge e of the stock. Furthermore, theedge y bears a distinct relation to the edge .fr as will be borne out inthe further description of the use of this device.

Each of these blades bears upon its face the data which the carpentermay desire or require instructing him in the use of the steel square bymeans of which the laying ofi' of the various rafter constructions isfacilitated. In the illustrated case the data relates to thecalculations which are required for laying ofi' plans of a roof ofone-quarter pitch and, therefore, the next blade in the implement hereinillustrated would contain the data for a roof. of one-third pitch, and

so on.

In the use of this simple device it will be understood from theforegoing general description that in the laying off of the commonrafters for a one-quarter pitch roof, the blade a is pulled outwardlyuntil its shoulder 1l abuts against the stop shoulder 7. This is thepredetermined position for marking 0H of the proper angles of the commonrafters. The thumb nut 5 is preferably tightened to hold the blade inthis position whereupon the bevel is laid upon the rafter to be markedas desired. Marking along the edge at' will give the angle line for aplumb cut. Without changing the angular relation of the blade withrespect to the stock the bevel may now be used for marking ofi' the sideor cheek cuts, the edge jz/ being employed for this purpose. It thusfollows that the edge 'y gives. the proper angle for side cuts when theedge ai is used for marking the plumb cuts so that there is a definiterelationship between these two edges in the use of the blade. Thisv samerelationship exists throughout the remaining blades and I, therefore,have in a single implement all that is required for laying off of anglesin the general set pitches of roofs that are customarily employed inbuilding constructions at this time.

As hereinbefore premised, in the known constructions it is necessary toadjust the single blade bevel member for each marking operation, and itis necessary to determine the position which the blade is to occupy withrelation to the stock before the laying oif of the angles can beperformed.

In those types of known bevels using a pluralityof blades itis necessaryto readjust the various blades in order to get one or the other of thecuts which are here obtainable by a single adjustment so that myimprovements form an important advance in tools of this character bymeans of which the laying off of angles is greatly facilitated.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A framing tool comprising a stock, a blade member pivotally connectedthereto, the marking edges yof which when the blade is set beardifferent angular relations to the stock, and fixed stop means forpredetermining the set to be given the blade for laying off theparticular angles prescribed by said edges.

2. A framing tool comprising a stock and a blade member connectedthereto for movement relative to the stock, and having opposite markingedges bearing an angular relationship to each other, each edge beingdisposed for marking off an angle line bearing a known relationship tothe angle line for which the other edge serves as a marking edge in thesuccessive use of the edges of the blade when in predetermined relationto the stock.

3. A framing tool comprising a stock, and a blade member pivotallyconnected thereto the operative marking edges of which converge towardthe pivot for the blade, each edge having a definite angularrelationship with respect to the stock such that one edge may beemployed for marking off plumb cuts while the opposite edge may beemployed for marking of side cuts.

4. A framing tool comprising a stock, a blade member pivotally connectedthereto and formed with a stop face, a cooperating stop upon said stocklimiting the opening movement of the blade to a definite angularposition, said blade having opposite marking edges which when the bladeis set. with the stops in contact bear different angular relations tothe stock and determine the set to be given the blade for laying offparticular angles prescribed by said edges.

5. A framing tool of the class described comprising a stock, a pluralityof blades pivotally secured to one end thereof, each blade beingconstructed and formed to serve in cooperation with an edge of saidstock for marking oif of angles for a definite roof pitch, a stop memberon said stock common to said lblades for predetermining the positionthereof in the laying off of the angles prescribed for each blade, eachblade having a portion adapted to abut against said stop member andmeans for holding said blades in adjusted positions relative to saidstop.

In testimony whereof I afiix my signature.
